constant communication with an intelligence analyst at operations command, and receives orders through an earpiece to don chemical-protection equipment because of new chemical weapons threat intelligence in the area. The chemical-protection suit is similar to but weighs less than those in use today. Most importantly, because it encloses the soldier's head, the suit has an augmented hearing syst...

The ability to maintain and manipulate information across temporal delays is a fundamental requirement to bridge the gap between perception and action. In the case of higher-order behavior, the maintenance of rules and strategies is particularly helpful in bridging this gap. The prefrontal cortex (PFC) has long been considered critical for such processes, and research has focused on different s...

The current study is a follow-up on the 2002 empirical study by Eshet-Alkalai and Amichai-Hamburger, which investigated digital literacy skills among different age groups. This study explores changes through time in digital literacy among the same participants 5 years later, and their performance is compared to new matched control groups. Results indicate an improvement over time among all age ...

Biomedical information extraction tasks are often more complex and contain uncertainty at each step during problem solving processes. We present an adaptive information extraction framework and demonstrate how to explore uncertainty using feedback integration. 1 Adaptive Information Extraction Biomedical information extraction (IE) tasks are often more complex and contain uncertainty at each st...

The information extraction tasks for the ARPA TIPSTER program center on automatically filling object-oriented data structures, called templates, with information extracted from free text in news stories (for discussion of templates and objects, see "Template Design for Information Extraction" in this volume). With text as input, the TIPSTER systems first detect whether the text contains relevan...

In Content-based Image Retrieval (CBIR) systems, accurately ranking images is of great relevance, since users are interested in the returned images placed at the first positions, which usually are the most relevant ones. In general, CBIR systems consider only pairwise image analysis, that is, compute similarity measures considering only pairs of images, ignoring the rich information encoded in ...

This PhD project aims at understanding and supporting the complex activities of information gathering. To date, most search applications support one aspect of search namely low-level keyword-based search to find documents. However, in reality, users search tasks are often high-level search tasks, such as comparing differences between art objects. Thus, there is a mismatch between the users sear...
